Title: Separator wall seal structure
Inventor: MASUDA SHINICHIROU
IPC: F28F9/00
Filed: 1983-06-03
Abstract: PURPOSE:To facilitate the manufacture and installationof a seal without causing a reduction in the sealing performance in a separator wall seal structure for a tank type FBR by disposing a sealing area approximate to a line-contact with grooves provided in the sealing surface. CONSTITUTION:The seal structure comprises a bellows 12, a seal flange 13, a spring plate 14 attached to one side of the seal flange 13, a shell of an intermediate heat exchanger 5 and a separator wall 6. By a trapezoidal groove disposed in the seal flange 13 and a protrusion of the separator wall 6, the positioning of the heat exchanger is decided as a matter of course, and even when the seal flange 13 is inclined, the sealing performance can be maintained by the deformation of the spring plate 14. Since the sealing surface comprises slanted flanks of the groove and protrusion, the contact area can be made smaller, and the intrusion of foreign objects into the sealing surface can be prevented.

Title: Protection device for in-room abnormal negative pressure
Inventor: KUWATA MASANOBU
IPC: G21F7/015
Filed: 1978-08-10
Abstract: PURPOSE: To simplify an air conditioning equipment and to keep the negative pressure inside a room within a fixed range by fitting auto-operative movable vanes in an air feed duct system.  
     CONSTITUTION: When the pressure inside a ventilation room 1 has decreased below a predetermined negative pressure, the dynamic pressure inside an air feed duct 5 decreases, and the decrease in the dynamic pressure is transmitted through a dynamic-pressure introduction duct 23 and a dynamic-pressure blow-off port 24 to movable vanes 22, which are opened by high atmospheric pressure. The outside air is introduced through an outside-air introduction duct 21 into the air feed duct 5, to return the pressure inside the room 1 to a predetermined nagetive pressure. Because the vanes 22 are opened and closed by the balance between the dynamic pressure inside the duct 5 and the atmospheric pressure, the air conditioning equipment is simplified and the negative pressure inside the room is kept constant.

IPC: B21K1/46
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a forming method for a head part of a thread member capable of surely straightening a wire rod, stabilizing quality and improving productivity. SOLUTION: A wire rod 2 is heated by high frequency induction heating 17 to about 400 deg.C before straightening the wire rod 2 with a wire rod straightening roller part 5. Thus, bending of the wire rod 2 is sufficiently straightened with a wire rod straightening roller part 5, when an end part of a wire rod 2' cut by first/second punches 14, 15 is inserted/striked, because bend is not left to a cut wire rod 2', the cut wire rod 2' does not gall die 16. Accordingly, damage of the die 16 is suppressed to extend a life of the die 16 as well as the device. Further, exchange frequency of the die 16 is reduced, interruption of a forming work of a thread member 10 is suppressed, productivity is improved.
